What do I need to do?
If you import goods of this heading, keep count of the net mass per calendar year. If you stay at or below 50 t with all CBAM goods combined, you are exempt – you declare the exemption in the customs declaration. Above that you need authorisation as a CBAM declarant, and you need it before the threshold is exceeded; the first annual declaration for 2026 is due by 30 September 2027.
